Audiobus: Use your music apps together.

What is Audiobus? — Audiobus is
an award-winning music app for iPhone and iPad which lets you use
your other music apps together. Chain effects on your favourite
synth, run the output of apps or Audio Units into an app like
GarageBand or Loopy, or select a different audio interface output
for each app. Route MIDI between apps — drive a
synth from a MIDI sequencer, or add an arpeggiator to your MIDI
keyboard — or sync with your external MIDI gear.
And control your entire setup from a MIDI controller.

Independent panning position of each channel, allowing for interesting stereo placement.

This is what I've been searching for! This app is unique in what it can do (as far as I know) in the App Store. I'm a big fan of this dev's previous apps but to me this is the most useful of all: I'm primarily a guitarist & have been craving a way to get stereo widening for my guitars on iOS - there hasn't been a really good way to do it until now, but this app meets that very specific need wonderfully. Yes, you can double track guitar parts and pan hard left and right manually (& I will continue to do so at times) but this app is extremely useful for creating that elusive very tight stereo panned effect! Fan-ruddy-tastic! This is really top drawer & would make a fine addition to ANY recording set-up (let alone iOS recording). Can also add depth & sparkle to any other types of sounds, instruments or recordings - I'd highly recommend this app to any iOS musician. NB. Do remember to check your stereo recordings on a mono speaker as well though - what sounds amazing on a pair of stereo headphones might sound downright weird on a mono speaker.

I dunno. Have you tried it? What I’m trying to do is to find a simple way to pan samples from Samplr and import them back in without too much fuff.

I haven't. Should work but doesn't exactly meet the 'without too much fuff' requirement.

Might also work: Open-in MulitTrack DAW, pan the track as needed, Mixdown, share, open-in samplr? Any DAW should be able to do this. Suggesting MTD because of the speed.

I know what you mean. I was trying to work out a way to do it ‘in the heat of the moment’. Not quite live but as if using an editor in say BM3 just instead of double tapping on a waveform just tapping open in to open the file in a specialised app to be then reimported at a tap or two.

Trying to develop a bit of a workflow you know. I bet Samplr’s gonna get panning or separate outs by that pagan festivity otherwise known as Christmas.
